Answer:
B) Interquartile range
Step-by-step explanation:
Since there are some students that do not eat fast food at all, their amounts spent monthly would be $0. These are much different than the rest of the data, and thus are outliers.
Outliers can greatly affect the mean. This tells us the mean may not be the best measure.
Since the mean is affected by outliers, the standard deviation is not the best measure either.
Adding data points of 0 will also affect the range. This leaves the interquartile range as the better measure.

Answer:
<h2>Option D is the right answer.</h2>
Step-by-step explanation:
We need to find the option for which the value of the function will be increasing, with the increasing variable.
Vertical line means the value of the x is constant, for any y. Hence, it is not the answer.
Horizontal line represents constant functions. Hence option B can not be the answer.
The data having a positive slope represents a <u>increasing function with the increasing variable</u>. Vice-versa for the data having a negative slope.
That is why option D will be the answer.
Answer:
∠1=140
Step-by-step explanation:
∠1=∠3 ( corresponding angles)
20x+60=30x+20
-20x+30x=60-20
10x=40
x=4
∠1=20x+60=20(4)+60=140
Answer: 6,247,000,000,000
Step-by-step explanation:
Here we have the number:
6.247x10^12 and we want to write this in standard form.
You can see that we have a 10^12, this means that we need to move the decimal dot 12 places to the right, if there is not a decimal to the right, we add a zero.
6.247x10^12 = 62.47x10^11 = 624.7x10^10 = 6,247x10^9 = 62,470x10^8 and so on.
eventually, the standard form is:
6.247x10^12 = 6,247,000,000,000
So we end with 12 digits after the six.
